Patented July 29, I947 UNITED STATES I PATENT OFFICE 2,424,605 FEATHERABLE PIN TYPE OARLOCK William Harrison Edmonson, Jr., Bridgewater, Va.

Application January 7,

6 Claims.

My instant invention relates to row boats and has for its object to provide a pin type oar lock which may be readily feathered.

Another object of this invention a pin type oar look from which the removable.

is to provide car is readily Figure 1 is a sectional elevation of my improved oar lock,

Figure 2 is a section on line and Figure 3 is a modification.

While one embodiment of the invention is illustrated n the ab 2-2 of Figure 1,

sectional elevation illustrating a utilized to the best advantage according to cirarise, without in any way bores being horizontally disposed and neither extending entirely through, duced slot 29, at the lower part of bore 26, which slot the head end 30, of a spring catch 3|, is adapted to project. The ring end 32 of the catch is secured to a pin 33, traversing the rear and of bore 25, and a spring 33 normally holds 1946, Serial No. 639,518

40 and 4|, of pins 42 and 43, are engageably received. These pins 42 and 43, have their other ends 42' 3", screwed into the opposing enlargements 44 and 45, of a supporting ring 46, for the oar 41. The pins 42 and 43, due to their reverse threaded ends 40 and 4| engaging the ring 38 and their opposite means between ring 48.

The spindle I4, is provided with an annular flange 48, which is adapted to seat .upon the upthe ring 38 and release the In Figure 3 of the drawings, I show a modification in which a ball retaining ring 58, operates in the channel 59,

6|, seating through ring 60, project from both When the quarter sections l9 and 20, of the open ring l2, are opened up free passage is provided for the oar 41, and its ring 46, for removal of the ear from the lock.

From the foregoing specification it will become apparent that the invention disclosed will adequately accomplish the functions for which it has been designed and in an economical manner and that its simplicity, accuracy and ease of operation are such as to provide a relatively inexpensive device considering what it will accomplish and that it will find an important place in the art to which it appertains when once placed on the market.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary,

Changes in shape, size and rearrangement of details and parts such as come within the purview of the invention claimed may be resorted to, in actual practice, if desired.

Having now described the invention that which is claimed to be new and desired to be procured by Letters Patent is:

1. In a device as described an outer ring, an intermediate ring and an inner ring for supporting an oar, said intermediate ring rotatable .upon the outer ring, said outer ring being formed in segments and provided with an inner channel in which the intermediate ring seats, means whereby the inner ring is the intermediate ring, said means comprising a pair of pivot .pins threaded into the inner and intermediate rings, said segments being hingedly connected, means for locking the same into a ring, a spindle supporting the outer ring, means carried by the spindle for securing the same in a socket, said last means including'a release for the spindle.

described an outer ring, an intermediate ring and an inner ring for supporting an oar, said intermediate ring rotatable upon the outer ring, said outer ring being formed in segments and provided with an inner channel in which the intermediate ring seats, means whereby the inner ring is supportedby the intermediate ring, said means comprising .a pair of pivot pins threaded into the inner and intermediate rings, said segments being hingedly connected, means for locking the same into a ring, a spindle supporting the outer ring, and means carried by the spindle for securing the same in a socket.

3. In a device as described an outer ring, an intermediate ring and an inner ring for supporting an oar, said intermediate ring rotatable upon the outer ring, said outer ring being formed in segments and provided with an inner channel in which the intermediate ring seats, means whereby the'inner ring is supported by the intermediate ring, said means comprising a pair of pivot pins threaded into the inner and intermediate rings, said segments being hingedly connected, means for locking the same into a ring, and a spindle supporting the outer ring.

4. In a device as described an outer ring, an intermediate ring and an inner ring for supporting an oar, said intermediate ring rotatable upon the outer ring, said outer ring being formed in segments and provided with an inner channel in which the intermediate ring seats, means whereby the inner ring is supported by the intermediate ring, said means comprising a pair of pivot pins threaded into the inner and intermediate rings, said segments being hingedly connected, and means for locking the same into a ring.

5,. In a device as described an outer ring, an intermediate ring and an inner ring for supporting an oar, said intermediate ring rotatable upon the outer ring, said outer ring being formed in segments and provided with an inner channel in which the intermediate ring seats, means whereby the inner ring is supported by the intermediate ring, said means comprising a pair of pivot pins threadedinto the inner and intermediate rings, said segments being hingedly connected.

6. In a device as described an outer ring, an intermediate ring and an inner ring for supporting'an oar, said intermediate ring rotatable upon the outer ring, said outer ring being formed in segments and provided with an inner channel in which the intermediate ring seats, means whereby the inner ring is supported by the intermediate ring, said means comprising a pair of pivot pins threaded into the inner and intermediate rings.
